    Question Huh? Why doesn't it work?

    Code:
    .MODEL SMALL
    .STACK 200H
    .DATA
    Textstring db "Hmm...It just doesn't seem to work.$"
    .CODE
    START:
    
    Mov ax, SEG Textstring
    Mov ds, ax
    Mov dx, OFFSET Textstring
    Mov ah, 09
    Int 21h
    
    mov ah, 4ch
    mov al,00h
    int 21h
    
    END
    Won't compile, says: "Fatal: No Program entry point."

    I'm new to ASM, and it's really complicated [cool, huh?]

    Hehe, forgot the "START" after "END"

    Code:
    .MODEL SMALL
    .STACK 200H
    .DATA
    Textstring db "Hmm...It just seems to work.$"
    .CODE
    START:
    
    Mov ax, SEG Textstring
    Mov ds, ax
    Mov dx, OFFSET Textstring
    Mov ah, 09
    Int 21h
    
    mov ah, 4ch
    mov al,00h
    int 21h
    
    END START

    We'd need an "Assembly" room, too, isn't it?
    Btw, you'd try to optimize your code - it is the real spice of assembly.
    e.g.
    instead of
    mov al,00h -> xor al, al
    and so on.

    Have fun, ASM is the king!

    Yeah I don't understand any of it yet, I'm doing a few online tutorials whilst waiting for my book to arrive. (stupid amazon).


    I ordered this one: http://www.amazon.co.uk/exec/obidos/...372088-2641245

    LoL, I live near S.F., and Amazon.com got me 2 books in about 2 days, and it was right around September 11th also...

    Pretty fast for me.
    What will people say if they hear that I'm a Jesus freak?
    What will people do if they find that it's true?
    I don't really care if they label me a Jesus freak, there is no disguising the truth!

    Try to find Peter Norton's book on ASM, I felt in love with Assembly while studying his book.
    He's got humour, style, and is a great teacher. He introduces you step by step in the world of assembly programming, while building a functional hex-editor.

    I just can't recall, but searching... Will let you know.
    I've found two similar books on the net, but the one I was writing is building a hex-editor step by step.
